Vapor Surveys are
critical investigative tools when assessing potential contamination
at dry cleaners, gasoline service stations and other
sites using volatile organic compounds and cholrinated hydrocarbons. |
|
Soil Vapor Surveys are conducted to assess upward vapor risk
from volatile chemicals. Contaminated soil and groundwater
can release volatile chemicals (such as PCE, TCE, benzene,
toluene, ethylbenzene, and xylenes) in the vapor phase. These
vapors migrate through the subsurface soil, the ground surfaces,
and flooring material in open areas of buildings. They can
cause health risks for building occupants.

Viridian® Inc.,
conducts active, passive and flux chamber
soil vapor surveys using EPA-supported methods and multi-state
guidance. Vapor samples can be collected at various depths
through multiple types of terrain, including concrete or asphalt
and various flooring material. We use hand-operated equipment
for limited access sites and sub-slab sampling in building
interiors. Vapor samples are stored in air tight Tedlar® bags
or Summa® canisters that are shipped directly to a laboratory
for analysis.
